The one that caught our eye is the i3.3 integrated amplifier. Why? Because Simaudio offers several optional add-ons not typically found in this product category. You can add an internal digital-to-analog converter, with USB, S/PDIF, and Toslink inputs, to connect a PC, digital music server, or external transport.

“Soundboard,” 109 inches tall and 148 inches wide, is Nornberg’s visual representation of sound. It’s loaded with 180 stereo components—from AM/FM receivers to 8-track players and tape decks—that Nornberg gutted. He rewired the 2,000 lights so they that they pulse in unison when connected to a sound source.

Even the most aesthetically challenged audiophile has to admit there's something about those sexy slices of contrasting solid walnut and the elegant teardrop design that transcends their mere ability to eliminate undesirable internal resonances.

The DAC1 USB is compatible with Windows and Mac OS X operating systems, and can accommodate 88-96kHz/24-bit USB audio (as well as 44.1-48kHz/16-bit digital). High-resolution audio is automatically passed from the source to the USB without data modification.

The S-275 has a claimed 275 watts for each of its two channels, or you can bridge them to have 550 watts in mono mode. The S-275 is half the width of most amps, so you can fit two in the space of one regular; sized amp.

Clearly, the 401 HR is not the product of market research or an iPod-obsessed sales department. It was designed with a single goal: to sound great. Truth be told, the original Moscode’s basic-black styling wooed no one other than die-hard audiophiles; the new design—available in silver or black—has an integrity of purpose sorely lacking in more mainstream component.

But the hippest, most modern way to fuel the Art.Engine is by using its wireless feature to access music stored on a computer. The product includes a Linksys router configured especially for use with the Art.Engine.

Electrostatic headphones (or loudspeakers) have lower mass diaphragms compared with dynamic drivers' heavier cones and domes of "regular" speakers. Domes and cones are propelled by a moving coil from either the center or edge of their diaphragms.

From its breathtaking ascending form to its aircraft grade 6061-T651 aluminum front baffle and enclosure—according to the company, “simply the most resonant free ... stiffest, strongest, and most acoustically desirable materials ever found”—every facet of the Anat Reference II Professional’s design points toward the goal of ultimate performance, not aesthetic timidity.
